Julia Cameron in her book The Artist's Way - A Course in Discovering and Recovering your Creative Self talks of the need to fill the well :- In order to create, we draw from our inner well. This inner well, an artistic reservoir, is ideally like a well stocked trout pond...any extended period or piece of work draws heavily on our artistic well... As artists we must learn to be self nourishing. We must become alert enough to consciously replenish our creative resources - as we draw on them - to restock the trout pond so to speak.I am beginning to think that my current restlessness has something to do with the need to fill the well. I've been painting full time for over a decade now - obviously filling the well frequently - but I feel a great need to drain it completely, clean it out thoroughly, repair the walls, and top it up to the brim with fresh new water - hundreds of thousands of gallons of it!..do you need to fill your well?....
